I may resurrect an former desktop machine as a trouble shooting aid.
I need to know the data bus width.
I know the Debian version number is stored in /etc/debian_version .
How do I find if the installed OS is 32 or 64 bit?
$ file /bin/true
That information is presented clearly.
How do I discover the CPU's bus width?
$ cat /proc/cpuinfo
The line
address sizes : 36 bits physical, 48 bits virtual
is clear.
I don't see the data bus width clearly identified.
Are the lines
clflush size : 64
cache_alignment : 64
pertinent?
TIA
